How to participate

To join this group

If you are officially added to the group, you will automatically receive group email and your login and password will work on this wiki.


Working Drafts: (including Activity Streams drafts)

Editors drafts:


  • List of github aliases of Social Web WG contributors: Socialwg/Github
  • Resolutions - e.g. to accept & publish drafts, for controversial issues, etc.


Proposed documents to the working groups

  • ...


We currently use IRC, email, telcons, and face-to-face meetings for discussion:


The working group uses IRC nearly daily, and very actively during and after the telcons.

The IRC channel is logged on the publicly-visible URL above. You can bookmark the URL and it will redirect to the current day.

You can get your photo to appear next to your name in the logs by:


We have two mailing lists for informal discussions for those that like email. You don't have to use them to participate in the working group.

Dedicated to Social Web Working Group discussions. See public-socialweb archive. Read-write for WG members. Read-only for non-members.
For Social Web public discussions. See public-socialweb-comments archive. Read-write for all, WG members and non-members alike.


Weekly telecons take place on Tuesdays at 1PM US/Eastern (10AM US/Pacific, 19:00 Paris, etc, see time converter for more options), as determined by poll.

Our three chairs -- Tantek, Arnaud, and Evan -- rotate through chairing the telecons in that order. Agenda items for a telecon should be posted to its wiki page by the Friday before, no guarantee of getting to anything posted after that. If the scheduled chair is unavailable when telcon time happens, the backup chair steps in. Rotation continues normally, though chairs may swap back to make up for missing their turn.

Telecon Information

IRC is a key element of how W3C teleconferences are run, please join the IRC channel (#social) before dialing in!

  • Join IRC (#social) before dialing in
  • Join WebEx meeting
    • Or, dial: 1-617-324-0000 and follow prompts

    • (In case you need to actually see the WebEx meeting URI, it is: )

Once you are connected to WebEx, select "Call Using Computer" (large 'button' on left), to have WebEx make the audio connection to you

  • Choices: WebEx can call you, or you can call in.
  • (Note: when using "Test Audio Connection", you will be muted).

If you cannot use WebEx, the host can initiate a call to you.

  1. The Chairs have a "host key". When one of them starts the WebEx session, they should enter that number, to be identified as the host.
    1. If anyone else is chairing, get host key from Tantek, Evan, Arnaud, Sandro, or Ann
    2. In "Participant" menu (top left), choose "Reclaim host role"
  2. Once you are the host, the "Invite and Remind" button becomes available (in middle of WebEx session screen)

In case you can not participate in next meeting, please add your name to Regrets section on Agenda page of next telecon. If you sending last minute regrets and don't have possibility to edit wiki page, please reply over mailing list on agenda thread already started by chair of this meeting. [1]

Identifying yourself

For record keeping it is important that everyone attending our teleconference is identified. W3C's IRC bot, Zakim, which helps facilitate meetings using IRC in conjunction with the W3C's audio teleconference bridge, can help identify you but there are cases when Zakim needs your input. It is therefore important that before you call in, you first join the IRC channel (#social) and monitor it. For more info on this refer to Zakim's page.

Past Meetings


As a scribe, after you're done minuting into IRC for a given date, e.g. 2014-10-14:

  1. Get the source of (should have been generated by RRSAgent after chair asked for "trackbot, end meeting" in IRC)
  2. Convert from HTML to Mediawiki syntax, either:
    • Locally run it through pandoc with command: pandoc -f html -t mediawiki -o input-minutes.html
    • or try this online converter (experimental! Comments/bug reports to rhiaro).
  3. Use Socialwg/2014-10-07-minutes as a template to create Socialwg/2014-10-14-minutes
  4. Add any resolutions from the meeting to Socialwg/resolutions


To document proposals, ideas, even specifications that are social web related, please create pages for them on this wiki and add a link to them from here.


You may preface your page names with "socialwg/" if you pick a particularly generic name and/or wish to indicate the scope in the name.

Inputs Into SocialWG

Inputs into SocialWG, including specs from External Groups explicitly listed in the Charter.

Activity Streams

Main article: Activity Streams

See #Drafts at the top of this page for Activity Streams editor's drafts, issues, and github repo links.


Dependent Work

Work we don't expect to accomplish as part of this charter but which we need to keep in mind while making decisions about the architecture. This includes both work that is already partly defined, and work that isn't but falls outside of our charter.


Documentation which is abstract (i.e. lacking documented real world use-cases).




The Social Web Working Group workmode is roughly as follows, and may be iterated based on group experience:

  • #Discussion - use IRC, telcons, email for discussion only
  • #Documentation - capture proposals and conclusions here on the wiki


Issues for each specification are managed in the GitHub repo for each specification. See top of page for those links.

Issues and Actions for the working group overall are managed via the W3C Tracker. See Social Web WG Tracker.


resolutions will be highlighted in minutes, and people not at meeting can bring up their concerns within the following week


A rough schedule for the work of the WG, originally based on Social Web WG Charter Milestones.

Applied for Membership

Tantek Çelik has encouraged people who have applied for invited expert membership to list themselves here, but there is no requirement to do so.

Include the date you submitted the form.

  • Michael Vogel Friendica maintainer github No Application Received. After applying, put the date here.

Invited Expert Approval

To be approved as an invited expert, one or more of the chairs and/or W3C staff contact and/or their management have to vouch for you. They likely have different criteria for vouching, and may or may not document (all of) their criteria publicly. E.g. chairs & staff contacts:


Tantek Çelik:

  • For me, an expert on the social web MUST be actively publishing social content on their own website. Merely sharecropping on silos or contributing to open source projects only makes you a hobbyist, not an "expert". -Tantek


Evan Prodromou

  • For me, an invited expert should be implementing social software, or represent a company implementing social software.


Arnaud Le Hors

  • Given the applicability of this technology behind the firewall of an enterprise, I don't share Tantek's view on what constitutes an expert in the matter.
  • In keeping with the W3C Process I will consider applications for Invited Expert status on a case by case basis. It's fair to say that I'm rather conservative in that matter, which means that by default requests will be declined. Invited Experts are typically well known to the community through participation in different forums, conferences, etc. When that's not the case, applicants have the burden of convincing the chairs and Team that they should still be granted this status by explaining why. Invited Expert status is a privilege, not a right.


Please add questions which have been answered in IRC by the chairs here:

  • ...

Am I Relevant To This WG

Q: Am I important or relevant to this working group?

A: Do you:

  • implement social web technologies?
  • or publish social content on a website you control? (social content, from you to others, regarding yourself and/or others, blogrolls (e.g. using XFN for social relationships, e.g. )

Or both? In either case, the working group can use your input relating to your personal experience with doing so.


Q: Will the teleconference call audio be made public after the meeting?

A: No. However, they will be annotated by a scribe and minutes will be made publicly available shortly after a working group meeting. For example socialwg/2014-09-02-minutes.

What is the role of the WG IG CG

Q: We should clarifiy the role of Social Web WG & IG and Federated Social Web CG?

A: Community groups are free form, can produce documents but binding only to members of that community group. Working groups are in charge of producing actual specifications and have set time to deliver.[2] The Social Web Working Group (WG) has a charter with fairly specific deliverables (syntax, API, protocol) that it is focusing on. The Social Web Interest Group also has a charter which is focused on the research and documentation of social web use-cases.


Some background and past of the working group.

Previous W3C Groups




2015 unofficial social media

Unofficial social media created by former working group participants:

Facebook group (UNOFFICIAL, run by WG participant elf Pavlik)
Twitter account (UNOFFICIAL, was run by Erik Wilde, WG participant til 2015-07-07)
  • Anyone have contact info for Erik? Can you get the keys to @SocialWebWG and send them to to chairs? - Tantek Çelik (talk)

Past Work Items

Past work items that the working group has dropped:

Home Page To Do

To Do for our group home page in particular.

Problem: "It's kind of overwhelming" (aaronpk, IRC 2016-04-19)

Goal: smaller, simpler, shorter page that you could send to someone not in the group, to let them know what the group is doing

Some tasks:

  • "Documentation" section - most of that should be moved to a Socialwg/research page - it's background for work that we're doing
    • the red links in Documentation should just be deleted
    • some stuff like the Use Cases and Inputs Into SocialWG should be separated out
  • "Related Organizations" could be moved to a subpage
  • "Invited Expert Application" and "FAQ" could also be moved to subpages
